Figure 2: A. 24 hour total urine volume (Uvolume) measured repeatedly in
2 separate experiments; B. the correlation of the Uvolume between the 2
measurements; C. 24 hour total urine albumin excretion (Ualbumin) measured
repeatedly in 2 experiments; D. the correlation of the Ualbumin between
the 2 measurements; E. 24 hour total urine volume (Uvolume) measured
simultaneously with the total drinking volume (Dvolume) in the same day; and
F. the correlation between the urine and drinking volume.
